摘　　要：通信协议的设计已然成为实现设备与互联网通信的重要支撑,其覆盖了整个物联网系统的各个环节。针对传统物联网协议中关键数据被伪造或篡改的安全问题,文章设计了一种在数据传输过程中使用区块链技术来保证传输数据安全的改进消息队列遥测传输(message queue telemetry transmission,MQTT)协议,进而保证了存储在broker的数据不被恶意篡改。通过仿真实验证明,该方法具有高效、轻量以及易实现等多方面的特点,在保护物联网的数据安全方面效果十分显著。The design of communication protocol has become an important support for the communication between devices and the Internet,which covers all aspects of the entire Internet of Things system.Aiming at the security problem that the key data in the traditional Internet of Things protocol is forged or tampered with,an improved message queue telemetry transmission(MQTT)protocol is designed to ensure the security of the transmitted data by using blockchain technology in the process of data transmission.This ensures that the data stored in the broker is not maliciously tampered with.Simulation experiments show that this scheme has many characteristics,such as high efficiency,light weight and easy implementation,and has a remarkable effect in data security protection of the Internet of Things.
